Serpent SER909520 Centax II/III 1.8 Spring (10mm) - Stiffer Clutch Upgrade  [SER909520]

Performance boost with Serpent SER909520 1.8 spring

The Serpent SER909520 Centax II/III Spring is a precision accessory for tuning clutch feel on Centax II and III assemblies. At 10mm long with a firmer wind than the stock unit, it increases clutch tension for a more decisive engagement while keeping coil spacing that supports smooth shoe travel.

Clutch engagement tuning

The higher spring rate helps you run tighter clutch settings to improve initial acceleration and throttle response. Despite the added stiffness, the coils remain spaced to allow consistent contact between the clutch shoe and bell, helping avoid harsh grabbing.

Fitment and intended use

Designed specifically for Centax II and Centax III clutch systems, this spring is ideal for drivers wanting a firmer feel for racing or more responsive street running. It is a straightforward swap for those familiar with Centax clutch maintenance.
